The Link Layer is the first layer of the Bluetooth® Low Energy protocol stack which controls the radio and the timing of the Bluetooth® communication. Our Link Layer is Bluetooth 4.2 fully featured qualified and is already compatible with all the new features of Bluetooth 5 .
Bluetooth®5 Link Layer
The Link Layer has three possible configurations according to your needs. It can work:
- In HCI mode (BLE controller)
- In single chipset (with the BLE host stack)
- In co-processor: another microcontroller chip uses Bluetooth® Low Energy by ACI layer.
Features :
- Adaptable on any RTOS and MCU
- Mesh Ready : allows to adopt several simultaneous roles (Advertiser/scanner/master/slave)
- Bluetooth® 5: High throughput, Long Range and Advertising extensions
Requires :
- 2,4 GHz radio
- 32 bits processor
- Low Power timer
- Low power management
- Encryption
- Random generator
- Cryptography
Alpwise has developed a Link Layer simulator on PC that allows to develop and debug more easily this IP software, useful for tracking changes in the Bluetooth® specification.
